Emigqeni ehlukene yokukhiqiza, abasebenzisi bangabona ukucaciswa okuhlukile kwemishini yokwenza isihlabathi, ngakho ukukhethwa kwemishini yokwenza isihlabathi yochungechunge lwe-VC7 kuhlala kudingekile.
Yinto efanele ongayenza uma ufuna ukukhiqiza okwengeziwe.Umthamo wayo womshini owodwa ungafinyelela amathani angama-520 ngehora, okungaphezulu ngo-30% kunamadivayisi angaphambilini anamandla afanayo.Izici zomshini wokwenza isihlabathi we-Shanmei: i-Datong super four rotor entsha, ukushaya kwetshe kwekhwalithi ephezulu, ukushaya kwamatshe okuphumelelayo, idivayisi ye-flash enemisebenzi eminingi, ukugqoka izingxenye ezingagugi, ukusebenza okuthembekile.
Uma kuqhathaniswa nemishini yendabuko ngaphansi kwamandla afanayo, umshini wokwenza isihlabathi unomthamo omkhulu wokucubungula nokukhishwa okuphezulu, futhi okukhiphayo kwanda ngo-30% futhi kuzinzile.
Umkhiqizo unomumo omuhle kakhulu wokusanhlamvu, ikakhulukazi umumo wekhiyubhu, umumo omuhle wokusanhlamvu, ukugreda okunengqondo kanye nemodulus yefineness elungisekayo.
Ukusetshenziswa okuphansi kwezingxenye zokugqoka, ukwakheka kwe-cavity okunengqondo, kunciphisa ukuthintana okuqondile phakathi kwezinto ezisetshenziswayo nezingxenye zokugqoka, futhi kunciphise ukuguga kwezingxenye zokugqoka.
